[FLINK-2152] Added zipWithIndex
This PR adds the zipWithIndex utility method to Flink's DataSetUtils as
described in the mailing list discussion:
http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/The-correct-location-for-zipWithIndex-and-zipWithUniqueId-td6310.html.
The method could, in the future, be moved to DataSet.
@fhueske , @tillrohrmann , once we reach a conclusion for this one, I will
also update #801 (I wouldn't like to fix unnecessary merge conflicts).
Once zipWIthUniqueIds is added, I could also explain the difference in the
docs.

> We should provide a simple utility method for zipping elements in a data set
> with a dense index.
> its up for discussion whether we want it directly in the API or if we should
> provide it only as a utility from {{flink-contrib}}.
> I would put it in {{flink-contrib}}.
